Course Overview

The Professional English course by Open Source is designed to equip non-native English speakers with the language proficiency required to thrive in international IT and business environments. Specifically aligned with the English for IT B2 / GSE 59–75 certification exam, this program targets IT professionals, software developers, network and security engineers, product managers, and technical support staff who need to communicate effectively in English-dominant workplaces.

Learners engage with key tools and platforms such as Edube Interactive™ for immersive language practice and TestNow™ for secure, proctored certification exams. The hands-on lab component includes real-world scenarios like drafting incident reports, explaining system architectures, and simulating team meetings to practice listening, speaking, and writing in authentic IT contexts. Through structured exercises, students build and refine skills in writing professional emails, interpreting technical specifications, and delivering concise project updates. These labs are integrated directly into the Edube platform, offering a browser-based environment with guided scenarios that mirror actual workplace communication challenges, ensuring learners gain practical, job-ready language competencies.
